Anyone know how to read Continental date codes on their slicks?
There is a 4 digit spot that looks like on the street tires, but I don't know the translation into English, lol

You need to call Hoosier, they reuse their codes and manufacture the Continental Slicks.

So far, only way is to speak with Hoosier and that is a shit show by all accounts on the Vette and other forums. Add in that its a Continental tire, and I'm not too hopeful. Corporate runaround is imminent, methinks.

I think that's the "tire type code"


The DOT symbol certifies the tire manufacturer's compliance with the U.S. Department of Transportation tire safety standards. The DOT serial number is located on the lower sidewall of the tire, on one side only. Below is a description of the serial number. Starting in the year 2000, four numbers are used for the Date of Manufacture, first two numbers identify the week and the last two numbers identify the year of manufacture. Prior to year 2000, three numbers are used for the Date of Manufacture, first two numbers identify the week and the last number identifies the year of manufacture. To identify tires manufactured in the 90s, a decade symbol (a triangle on its side) is located at the end of the DOT serial number.

For Example: DOT NJ HR 2AE2 529

529 = Date of Manufacturer, example: 529 (52nd week of 1999) or 5200 (52nd week of 2000).

2AE2 = Tire Type Code (coding for type of tire optional by manufacturer).

HR = Tire Size Code Number.

NJ = Manufacturer's Plant Identification Code.

DOT = Reference Symbol (certifies the tire manufactures compliance with U.S. Department of Transportation tire safety standards).

slicks are non DOT, my son, hence they don't have to follow the typical marking scheme. :)

Hoosier's website says to contact them, since the 4 digit alpha numeric codes are reused every year or two.

If it's just a safety issue as to why you're looking for the date of manufacture I would just inspect them if they're scrubs. Conti slicks feel like hockey pucks when they get old, just beware of cracks or any damage to the bead from hitting curbing on track. If you do a few laps on track, get em up to temperature then pit and inspect them again.

They are brand new, never been mounted, always stored indoors. Just want to know how old they are before I send them out for heat cycling and mounting/balancing.

They look freshy fresh.

Call Braidan Motorsport: www.braidanmotorsport.com at 905-209-7979, they sell these tires and might be a better route to go than Hoosier for info. They also have locations in Markham and at the CTMP GP track and can heat cycle them for you. I buy all of my track tires from them.
